Water Tank in Farmstead World — building in the game, and what it is on a real farm.
A water tank stores water on site and gives the pipes a steady head of pressure, so troughs and taps keep flowing even while the pump rests.
Tanks are sized to carry a farm through a dry spell and are fitted with floats or valves that let them refill themselves.
Farm facts about water tank

In the age of steam, water towers stood every 7 to 10 miles along the rails so locomotives could refill their tenders. (en.wikipedia.org)
From the 1850s to the 1930s, windmills on American farms pumped well water up into wooden tankhouses — an elevated tank gave the homestead steady water pressure. (en.wikipedia.org)
